I. Cautions and Warnings A. Cautions Never use any sample hose other than those approved for use with the ID900. The use of other hose types may introduce errors and excessive refrigerant loss. Always verify that the refrigerant source to be tested will not emit oil or liquid refrigerant before connecting the ID900 sample hose. Never connect the ID900 to any refrigerant source that exceeds 300-psi pressure. Do not utilize the coupling supplied on the ID900 R134a sample hose for an

II. Functional Description Contamination of refrigerant in air conditioning systems or storage cylinders can lead to component corrosion, component destruction, elevated system head pressure and system failures when utilized by unsuspecting technicians. The ability of a technician to determine refrigerant type and purity is severely hampered by the presence of air when attempting to utilize pressure- temperature relationships. The development of substitute refrigerants further complicates

B. Sample Hoses 1. R12 Sample Hose: is a 6-foot hose consisting of a nylon inner tube surrounded by a polyurethane outer tube. The hose contains the instrument connection fitting on one end and a ¼” SAE female flare nut on the other end. This hose is to be utilized when sampling from R12 vehicle systems or storage cylinders. 2. R134a Sample Hose: is a 6-foot hose consisting of a nylon inner tube surrounded by a polyurethane outer tube. The hose contains the instrument connection fitting o

IV. Operation Procedure A. Pre-Operative Inspection 1. Inspect the outside diameter of the white element contained within the sample filter for any signs of red spots. The appearance of red spots anywhere on the outside diameter of the element indicates that the filter requires replacement to avoid fouling of the instrument. 2. Select the R12 or R134a sample hose as dictated by the application. Inspect the hose for cracks, signs of wear, obstruction or fouling. DO NOT use any hose that

5. When prompted by the instrument, connect the free end of the sample hose to the vehicle air conditioning system or refrigerant storage cylinder port and press the “A” pushbutton. Sample gas will immediately begin to flow into the instrument. The instrument will require approximately 30 seconds to complete the sample gas analysis. 6. When the analysis has completed immediately disconnect the sample hose from the refrigerant source. Note: The instrument contains no automatic shut-off and

V. Maintenance A. Error Codes and Corrective Actions The instrument is supplied with self-diagnostic software to aid the user in the determination of problems. The software will supply error codes that will direct the user towards specific corrective actions in the event of system failure. ERR.1: Signifies unstable infrared readings due to inconsistent sample gas supply or interference from strong electrical fields. Corrective Actions: 1. If the error code occurs during a sample cycl

Warning: Should it be determined that the air detection calibration failure has been caused by the presence of oxygen depleting compounds in the surrounding atmosphere the use MUST take immediate action to rid the area of such compounds or provide adequate ventilation to prevent such accumulation. The accumulation of oxygen depleting compounds in the surrounding atmosphere will present a human health risk and hazard. 3. To clear the error code power down the instrument. The error code will

c) When the hose is completely dry inspect the hose for signs of wear as described above. 3. Air Detection Sensor Replacement Inspection Frequency: The instrument will inform the user of possible air detection replacement requirements with the error code Replace Air Sensor. Air Detection Sensor Replacement Procedure: a) Refer to the error code corrective actions and try each suggested action. If the instrument still indicates the error code then the air detection sensor will require re
